I have a CD copy of Trine but i seem to be unable to update it to Enchanted Edition. It mentions on the Trine website that the Enchanted edition is only available on Steam, Gog and Humble Bundle. Does there mean i have to purchase another copy of the Game or I can fine the update somewhere on Steam even though my copy isn't a Steam copy?

Unfortunately, CD versions and downloadable versions from some shops aren't supported, as we have no way to update the new content for them. However, we do offer codes for these customers so they can access the new version too.

So, if you'd like to play the Enchanted Edition please email us to Support [at] Frozenbyte [dot] com with your proof of purchase and we can send you a Steam key for the game. If you don't have the receipt anymore, you could take a picture of the game's retail box you have.
